UV Curing Lamps
The UV Curing Lamps
supplied by Image Inks are medium pressure mercury-arc lamps producing
high intensity ultraviolet light. These lamps are well proven and widely
used for the curing of inks and coatings.
They are designed
and manufactured as direct replacement lamps to meet the specific needs of
original equipment manufacturers worldwide.
UV Curing lamps are
manufactured from high-clarity, vitreous silica, normally referred to as
quartz. Though expensive, quartz has the property of high transparency to
Ultraviolet light, particularly at the short wave end of the spectrum
where over 90% of the UV energy generated is transmitted through the
quartz. The electrode components are also manufactured from the highest
quality materials ensuring long and reliable lamp life.
UV Lamp Life
mercury arc lamps do not normally fail suddenly and there can be confusion
in defining lamp life. Electrically, the lamp may operate for many
thousands of hours though, at an earlier stage it will have ceased to emit
adequate UV light. Electrical lamp life is therefore irrelevant.
UV output from the
lamp declines gradually, as the UV transparency of the quartz body
deteriorates. The quartz changes from optically clear to opaque, thus
filtering out all useful UV. The rate of decline depends on a number of
factors; the switching frequency of the lamp, lamp and electrode cooling
efficiency, accurately matched power control, and the cleanliness of the
Lamp life must
therefore be measured in hours of useful UV output and Image Group
supplied UV lamps are guaranteed to produce a high level of curing
efficiency for at least 1000 hours with correct handling.
Image Inks UV
Curing Lamps are manufactured in lengths from 6cm to more than 300cm and
at power outputs up to 500 watts per cm.
Ozone Free lamps
are available as well. These lamps are manufactured in a way that reduces
the amount of ozone produced by the lamp, although lamp life is reduced.
In most cases, outside venting is not required when ozone free lamps are

Image Inks supply a
large range of equivalent lamps to such makes as Fusion, Hanovia, Heraeus,
Mazda, Metal Box, Philips, Sylvania, Terno, Toshiba, Ushio, Voltarc etc.
However, it is not always possible to cross reference all lamps by make or
type alone. For this reason we offer you a service that can enable us to
identify an equivalent lamp, or help us to design a new lamp to your
